Up close with one of the biggest stars in Washington, D.C. She's only 6 months old. Giant panda cub Bao Bao. Claire shipman with an exclusive look inside the panda cage. Here's Bao Bao. Reporter: So nice the meet you. Her name means precious in chi feez. Our exclusive visit to the smithsonian national zoo came with a host of rules. As she stretched and toddled around, the cute factor was unbearable. Am I allowed to touch her? No. Reporter: Sorry. That's okay. Reporter: Juan uses sticks with balls on the end and sweet potatoes to teach her skills. Good job, Bao Bao. Reporter: Sometimes it works. Sometimes she just wants to play with everything at once. The training is not about play or learning tricks. Her father shows us one of the many things Bao Bao will soon master. Before cued, he office up his arm through a slot in the cage. And the vets can take blood right out of his arm wile he's awake. And he'll allow it. Reporter: It's a huge help for his doctors. He knows he'll be rewarded with delicious honey water. He'll scooch over or lie down on command. Bao Bao will soon learn the do the same thing. This training helps the bears get comfortable with human contact. Like her parents, Bao Bao will spend her life with specialists. At age 4, she'll go live in a reserve in China. How can you not just want to cuddle all the time? It's hard. It's excruciatingly hard. The main thing is to remind yourself that they're a critically endanger species. You have to respect that they are endangered. We don't want to make them into pets. Reporter: As cute as she is.
